MinĂ€: âNo niin, takana on Nato-huippari, Garden-sotku, Iranin sodan jatkuminen ja vielĂ€ Ylen pÀÀtoimittajan kuolema. Nyt on kesĂ€, tĂ€mĂ€n uutisviikon on viimein pakko rauhoittua.â Todellisuus:
The Harmonie weather model is now forecasting widespread >40°C in the Netherlands for Friday, likely the warmest day of this heatwave. đ„ ECMWF slightly less warm. In any case, there will be 4 consecutive days with max temp >35°C in many places, which is bad enough.
Today, the ECMWF Council has appointed two Deputy-Director Generals: Dr JĂžrn Kristiansen has been appointed Deputy Director-General and Director of Forecasts. Dr Irina Sandu has been appointed Deputy Director-General and Director of Science and Innovation. âĄïž www.ecmwf.int/en/about/med...
It's official, Finland had just its warmest March on record. www.ilmatieteenlaitos.fi/tiedote/2huP... The new record was set with 1.2 °C margin (compared to 2007), which is the largest margin in any of the 21st-century monthly records. March 2026 is the first March with mean temperature > 0.0 °C.

KÀynnissÀ oleva avaruusmyrsky on protonivuolla mitattuna voimakkain hiukkasmyrsky sitten vuoden 1991 ja luokitukseltaan voimakkain (S4) sitten vuoden 2003. Myrskyn nÀkyvin vaikutus ovat tavanomaista etelÀisemmillÀ alueilla loimottavat revontulet. www.ilmatieteenlaitos.fi/tiedote/17u8...

Revontulia on nÀhty Keski-Eurooppaa myöten. Suomessa pilvisyys voi estÀÀ revontulien nÀkemisen suuressa osassa maata.

#CopernicusClimate has released its first data from the Copernicus pan-Arctic Regional Reanalysis (CARRA2): 2.5 km panâArctic coverage, 24 years of data in the Climate Data Store, more realistic physics & improved details for local extremes, lots of added details with respect to ERA5. âŹïž
Sunshine durations so far in December. Zero hours almost everywhere in Finland. No wonder if it's felt dark recently.
An eruption from the #HayliGubbi volcano in #Ethiopia resulted in a large ash cloud, visible here from space. đ This impressive view was seen 36,000km above Earth by our Meteosat-12 satellite on 23 November at 13:40 UTC.
I've seen a lot of dropsondes over my years, and a peak wind of 210kt - even at the top of/just beyond the boundary layer - is wild to see. Might be up there in the ranks of all-time strongest dropsonde-measured gusts as well.
From a crewmember on yesterday's Teal 74 mission into now-Category 5 Hurricane #Melissa. As clear of an eye as you will see in the Atlantic basin.
5pm and 198,000 premises are without power with top gust of 148kmh at Malin Head in last hour. The sunny spells have reached most areas as the center of #StormAmy moves Northeast of Ireland.
So this is pretty amazing - yesterday EarthCARE sampled Hurricane Humberto straight across the eye! The eye of a tropical cyclone is small so a direct hit is rare: this is the first time EarthCARE has hit one after over a year in orbit! (Showing here also VIIRS on NOAA-20 for context.)

20 straight days with 30 °C in Finland! Truly unprecedented heatwave still in full swing with maximum today about 32-33 degrees. Even the Arctic regions (e.g. SodankylÀ TÀhtelÀ) have seen three weeks above 25 °C, and may rival tomorrow their August heat records.
Kanadassa riehuu suuria metsÀpaloja. MetsÀpalojen savuja kulkeutuu Suomen yli nyt sunnuntai-illan (Lounais-Suomi) ja huomisen maanantain aikana. Ennusteen mukaan savua on selvÀsti silmÀllÀ havaittava mÀÀrÀ mikÀli pilvisyys sallii. Savu kulkee korkealla, joten sillÀ ei ole vaikutusta ilmanlaatuun.
